  • the audio processor 2032 outputs the processed audio signal to the audio output part 2040.
  • the image processor 2034 processes the input image signal (for example, decodes and scales the video). When the 3D image data is input, the image processor 2034 outputs the input 3D image data to the 3D image creator 2036.
  • the 3D image creator 2036 generates the left-eye image and the right-eye image interpolated to a size of a full screen, using the input 3D image data. To create the 3D stereoscopic image, the 3D image creator 2036 generates the left-eye image and the right-eye image to display on the screen.

  • the GUI generator 2038 generates the 2D GUI.
  • the 2D GUI looks likes the stereoscopic 3D GUI, rather than the general plain 2D GUI. However, the user can see the 3D type GUI without using the 3D glasses 2090.
  • the GUI generator 2038 generates the GUI including the left-eye 3D GUI and the right-eye 3D GUI similar to the 3D image. Accordingly, the 3D GUI data including the generated left-eye 3D GUI and right-eye 3D GUI is input to the 3D image creator 2036.
  • the 3D image creator 2036 generates the left-eye 3D GUI and the right-eye 3D GUI.
  • the 3D image creator 2036 alternately outputs the generated left-eye 3D GUI and the generated right-eye 3D GUI to the image output part 2050.
  • the audio output part 2040 outputs the audio fed from the A/V processor 2030 to a speaker.
  • the image output part 2050 outputs the image fed from the A/V processor 2030 to display the image on the screen. As for the 3D image, the image output part 2050 alternately outputs the left-eye image and the right-eye image onto the screen.
  • the storage 2070 stores the image received from the broadcast receiver 2010 or the image input part 2020.
  • the storage 2070 can be external or internal, and may be a volatile memory (such as RAM) or a non-volatile memory (such as ROM, flash memory, or a hard disk drive).

  • the 3D glasses 2090 alternately open the left-eye glass and the right-eye glass according to the received clock signal.
  • the glass signal transceiver 2095 receives status information from the 3D glasses 2090.
  • the controller 2060 acquires a user command based on the manipulation of the user fed from the manipulator 2080, and controls the operations of the TV according to the acquired user command.
  • the controller 2060 controls to output only one of the left-eye image and the right-eye image and to output the GUI generated by the GUI generator 2038 together with the one image.
  • the controller 2060 controls to alternately output the left-eye GUI and the right-eye GUI together with any one of the generated left-eye image and right-eye image.
